The prospect of photovoltaic + agricultural greenhouses is immeasurable!

Time: September 27, 2022

Photovoltaic agricultural greenhouse is a new type of solar system project that combines photovoltaic power generation with agricultural production, roof solar power generation, and agricultural production in the greenhouse. It is a new mode of modern agricultural development and a current investment hotspot.

1.The advantages of solar panel agricultural greenhouses

Compared with the construction of centralized large-scale photovoltaic ground-based power stations, photovoltaic agricultural greenhouse projects have many advantages:

① Advantages of land use

The photovoltaic agricultural greenhouse power generation module uses the roof of the agricultural greenhouse, does not occupy the ground, and does not change the use nature of the land, which can save land resources, especially in the current environment where arable land is greatly reduced, the efficient use of land is effective. to a positive effect.

On the other hand, the construction of photovoltaic agricultural greenhouses is also conducive to the development of modern agriculture and supporting agriculture, allowing farmers to achieve multiple incomes from one piece of land, and is also a way to improve the value of land use.

②The advantages of planting mode

Solar panels with different light transmittances are erected on agricultural greenhouses, which can meet the lighting needs of different crops, and can grow various high value-added crops such as organic agricultural products and precious seedlings, and can also realize off-season planting and high-quality planting.

③Economic advantage

The electricity generated by photovoltaic agricultural greenhouses can not only be connected to the grid and sold to power grid companies to achieve income, but also to meet the power needs of agricultural greenhouses, such as supporting the irrigation system of the greenhouses, supplementing the light for plants, solving the heating needs of greenhouses in winter, and improving the greenhouses. The temperature promotes rapid growth of crops and saves electricity bills for investment enterprises.

④ Cost advantage

Compared with centralized ground solar energy power stations, part of the power generation of photovoltaic agricultural greenhouses can be consumed locally, reducing losses on transmission lines.

⑤Project location advantages

The demand for land for ground power stations is high, and generally only unused land such as barren hills, barren slopes, and tidal flats can be selected. The terrain is complex, the geological conditions are poor, and the power station construction is difficult. The agricultural-photovoltaic complementary project can use the general farmland to realize the construction of photovoltaic power station without changing the nature of land use or affecting the growth of crops.

⑥Can be developed into tourism agriculture

Photovoltaic agricultural greenhouses can often take advantage of good transportation and location advantages, relying on the viewing and picking of ornamental seedlings, organic agricultural products, etc., to develop some tourism resources that integrate sightseeing, leisure and experience, form sightseeing agriculture, and increase farmers' income.

2. Types of photovoltaic agricultural greenhouses

The construction form of photovoltaic agricultural greenhouses is mainly integrated thin-film photovoltaic greenhouses, professional transformation on the original greenhouses, etc. Newly built greenhouses are generally constructed in accordance with integration. Compared with ordinary greenhouses, the steel frame structure of photovoltaic greenhouses is more complex and the cost is relatively higher than ordinary greenhouses.

1. Single shed (components are installed on the front roof, generally planted with negative plants such as edible fungi)

2. Spring/autumn/winter warm shed (components are installed above the greenhouse, and vegetables and flowers are grown according to the thermal insulation performance)

3. Warm yin and yang sheds in winter (modules are installed above the shed, the awnings are planted with light, and the shade sheds are planted with shade-loving plants)

4. Combined row shed (modules are installed on the sunny slope of the greenhouse, and crops such as traditional Chinese medicine and tea with general demand for sunlight are planted)

5. Glass greenhouse (components are installed on the sunny slope of the greenhouse, suitable for planting flowers, etc., for demonstration and seedling raising)

6. Multi-building open type (the components are installed on the sunny slope of the greenhouse, which is generally suitable for the warm climate in the south)

7. Elevated agricultural greenhouse (the components are installed on the elevated bracket, which is affected by the local land policy)
